Health care providers across several regions are sounding the alarm as cases of measles and whooping cough climb. Low immunization coverage, delayed shots and growing vaccine hesitancy are being cited as key drivers of the outbreaks. Parents, clinicians and public health officials are racing to contain the spread before more vulnerable people are infected.

Rising numbers: what the data is showing

Public health clinics and hospital emergency departments report more visits for fever, cough and rash. Outbreaks of measles and pertussis, commonly called whooping cough, have surfaced in communities with lower-than-average vaccine uptake.

• Measles is reappearing where immunity gaps exist, often beginning with unvaccinated travelers or clusters of unvaccinated people.
• Pertussis tends to flare in cycles, but low booster coverage can turn routine cycles into larger local outbreaks.
• Health departments link many new cases to delayed or skipped childhood immunizations.

Why immunity gaps are widening

Experts point to several overlapping causes that help contagious diseases move through populations.

• Vaccine hesitancy fueled by misinformation on social media and distrust in institutions.
• Missed routine appointments during the pandemic that left many children behind on their schedules.
• Uneven access to primary care and immunization services in some neighborhoods.
• Complacency when diseases seem rare, lowering the perceived urgency of vaccination.

How timing and coverage matter

Both measles and pertussis require high levels of community immunity to prevent spread. Even small declines in coverage can allow sustained transmission.

Who is at greatest risk when coverage drops

Not everyone faces the same level of risk if outbreaks grow.

• Infants too young for the full vaccine series are particularly vulnerable to severe disease.
• Pregnant women and newborns face elevated risks, especially with pertussis.
• People with weakened immune systems cannot rely on vaccination alone and depend on herd immunity.
• Communities with low access to care or high rates of unvaccinated people can experience larger outbreaks.

Recognizing symptoms early: what to watch for

Early recognition helps direct patients to care and limit transmission.

• Measles: high fever, runny nose, cough, watery eyes and a characteristic red rash that usually starts on the face.
• Pertussis (whooping cough): prolonged coughing fits, sometimes ending with a high-pitched “whoop” or vomiting after coughing.
• Both illnesses can be milder in vaccinated people, but they remain contagious.

Practical steps clinicians and families are recommending

Doctors emphasize proven public health measures to slow spread and protect vulnerable people.

1. Catch-up vaccinations: Bring children and adults up to date on MMR and pertussis-containing vaccines.
2. Boosters: Ensure adolescents and adults receive recommended pertussis boosters.
3. Pregnancy protection: Administer Tdap during each pregnancy to protect newborns from pertussis.
4. Rapid testing and isolation: Clinicians should test symptomatic patients quickly and advise isolation when appropriate.
5. Community outreach: Targeted campaigns can improve access and counter misinformation.

Vaccine schedule basics

• MMR (measles, mumps, rubella) is typically given in two doses in early childhood.
• Pertussis protection is given as part of DTaP in childhood, with Tdap boosters later.
• Timing matters: delayed doses can leave gaps in protection during critical months.

How public health officials are responding

Health agencies are stepping up surveillance and community engagement to limit transmission.

• Enhanced case finding and contact tracing in affected areas.
• Mobile clinics and extended clinic hours to make vaccines easier to get.
• Information campaigns to explain benefits and safety of vaccines.
• Partnerships with schools and childcare centers to review immunization records.

Questions families should ask their clinician

Clear, direct conversations with medical providers can reduce confusion and support timely decisions.

• Is my child up to date on MMR and DTaP/ Tdap?
• What is the schedule for catch-up vaccinations if a dose was missed?
• How can I protect infants and family members who are at high risk?
• Where can I get vaccinated quickly in my community?

When to seek emergency care

Certain signs require urgent attention.

• High fever that won’t go down or difficulty breathing.
• Severe or prolonged coughing spells with choking, blue lips, or fainting.
• Dehydration or signs of altered mental status.

How everyone can help slow outbreaks

Communities can reduce spread by combining individual choices with coordinated action.

• Stay current with recommended vaccines.
• Keep sick children home and follow isolation guidance when needed.
• Share accurate vaccine information from trusted health sources.
• Support policies that improve access to preventive care.
